when trying to refresh tv or radio I get error 500 for all the various stations

I have just looked on the BBC iplayer page and when going to celebrity masterchef program website it also returns error 500
The iplayer site appears ok in itself
I checked a couple of other program websites there and they also return error 500.

I am presuming this is a wider BBC problem and not an GIP problm, but I thought I should check
